So after I updated to 1.1 I excitedly started a new game. I start out in an area that is somewhat spare in planets with not too many higher quality ones, but after a little while I find a lot of planets worth going after. I also started out near the Drengin, as in our homeworlds were three or four sectors away on a gigantic map. I managed to not only get almost all of the good worlds in the area, but to completely surround the Drengin in the process. I started working on culturally converting his worlds and several were quickly in danger of falling to me (a couple without any starbases simply because there were several high quality planets nearby). The Drengin, seeing me as a strategic threat to their hopes for empire took a look at my military strength and noticed that I didn't have any (does the AI take into account what tehnology opponents have when judging their strength? I didn't have hardly any weapons tech either but it seems like tech is an important factor). So they decided to declare war. I bought the Stinger III from one of the other races and made a small ship i called the Emergency Missile Fighter and started making them on every nearby planet. I also researched the invasion line very quickly and started building transports. As my new fleets and transports headed for Dregin space, three of their outlying worlds fell to me due to culture. WIthin a few weeks I had taken two of their worlds, wiped out their defences and was preparing for the invasion of their last few worlds (they were down to five).
Suddenly, I get a message from the Drengin saying that they don't want me to have their worlds and so, apparently out of spite, they surrender to the Terrans of all people. I almost didn't believe it. The Terrans? I thought they were mortal enemies. This is the first game where I've really been able to dominate militarily (I usually do it culturally). Do races often surrender their planets to other races out of spite? Or a lot of spite in my case?
